Many people have good luck charms or similar types of items or actions that they believe allows them to do better with an upcoming event, such as a test or project. But those are all just superstitions and don't actually affect anything in real-life, right? Wrong!
Turns out, there is scientific evidence that good luck charms actually work. And no, it doesn't actually improve a person's luck. But instead, the charms help improve a person's confidence and self-assurance, leading to better performance.
Scientists in Germany conducted a study where participants played a round of mini-golf. They found that the subjects who were told their mini-golf equipment was "lucky" performed 35 percent better than those who were given just "ordinary" equipment. Those same researchers also found 40 participants who claimed they use good luck charms and had them perform memory tests with one group having access to the charms and the other getting no access. The group that was allowed to use their good luck charms performed better than those who did not.
